High Grade Drill Intercepts At The Gold Rock Project

VANCOUVER - Calibre Mining Corp. reported on the ongoing 35,000-meter drilling program at the Gold Rock project located in the Battle Mountain, Eureka gold trend, Nevada. The Federally permitted project is located within a prospective 78 km2 land package with numerous high-priority targets open for discovery and resource expansion.

Highlight Results from the Ongoing Multi-Rig Drill Program:

North Pit Zone

•2.01 g/t Au over 45.7 m in hole GR21-002; 0.99 g/t Au over 18.3 m in hole GR21-001;

•1.45 g/t Au over 38.1 m in hole GR21-008; 1.75 g/t Au over 19.8 m in hole GR22-037; and

•1.74 g/t Au over 35.7 m in hole GCM21-001; 0.71 g/t Au over 16.8 m in hole GR22-038.

Central Zone

•2.94 g/t Au over 18.0 m in hole GCM21-002; 0.64 g/t Au over 35.1 m in hole GR21-027;

•1.26 g/t Au over 35.1 m in hole GR22-031, 2.19 g/t Au over 44.2 m in hole GR21-021;

•1.53 g/t Au over 18.3 m in hole GR22-001; 1.64 g/t Au over 19.8 m in hole GR22-024; and

•1.00 g/t Au over 24.4 m in hole GR22-025; 0.90 g/t Au over 18.3 m in hole GR22-030;

South Pit Zone

•3.10 g/t Au over 18.3 m in hole GR22-005; 3.36 g/t Au over 22.9 m in hole GR22-007; and

•1.40 g/t Au over 27.4 m in hole GR21-025; 1.61 g/t Au over 35.1 m in hole GR21-029.

Darren Hall, President and Chief Executive Officer, said, “It is exciting to see continued high grade intercepts over significant widths across the primary project areas, in addition to significant potential across the 16.5 km mineralized trend. Drill results from 2021 and to date 2022 have intercepted grades higher than the reported indicated mineral resource average grade of 0.66 g/t gold. Encouraging metallurgical results demonstrate the mineralization is amenable to heap leaching with favorable recoveries and leach cycles. We continue to advance infill drilling and technical studies to support permit applications in the near term and enable reserve declaration at the end of 2022. Gold Rock was not included in our recently released multi-year outlook of forecast gold production.”
